The Britain-based group added the skirmishes left nearly 70 militants on both sides dead along with five civilians.

Al Nusra captured the village of al-Sabha, in the west of Deir Ezzor, with 11 of its fighters and 23 ISIL members killed there. In other villages of the oil-rich province, 35 al Nusra and allied militants died in clashes.

Over 150 people have been killed since the latest infighting between the rival groups broke out last week in Deir Ezzor.
